Oh no, certain items are worth massive amounts, others are only worth a max of 64, such as collectors and relays being worth 128 stacks, and i'm talking about the mk 3 variants in that case. we take the approximate emc value of an item or its components and total that up, compare it to the emc cost of one credit (four iron ingots) and then divide its total by the crdits value, this is only for the higher end items such as hv solar arrays, others have a price we set, such as one credit for six cooked chicken and when businesses get set up they will be able to determine a price for their items and services. But if they make it too expensive others will just do it themselves.
